GREGOR is a solar telescope that has been equipped with a 1.5m primary mirror and is located at the Teide Observatory on Tenerife in the Canary Islands. It’s currently the third-largest solar telescope in the world, after the Big Bear Observatory and the McMath-Pierce solar telescope. Its primary goal is to observe the solar photosphere and chromosphere at visible and infrared wavelengths. Read more for two videos and additional information.

The telescope boasts a high-order adaptive optics (AO) system with a 256-actuator deformable mirrors and a 156-subaperture Shack-Hartmann wavefront sensor. It was recently upgraded with two off-axis parabolic mirrors and captured stunning close-up images of multiple sunspots.
